中文摘要	草原露天煤矿的土壤湿度遥感监测可以反映露天开采活动对生态环境的扰动程度。选择国产环境卫星(HJ-1B)多光谱及热红外光谱数据,探讨HJ-1B数据在中国北部呼伦贝尔草原伊敏露天煤矿区地表温度及湿度的反演模型及适宜性,对比分析JM&S,Qin和Artis算法在研究区温度反演中的精度及适用性;进一步利用归一化植被指数和地表温度(NDVI - LST)的特征空间反演温度植被干旱指数(temperature vegetation dryness index,TVDI);通过野外实测土壤湿度数据对NDVI - LST特征空间中的干边模型进行修正。结果表明:基于Qin算法反演的温度数据精度最高;干边纠正系数为0. 3时,TVDI与实测土壤含水量相关性最高,湿边呈现剖物线特征,干边呈现线性规律。反演结果能够很好地反映露天煤矿区内不同地物的地表干旱状况及空间异质性,可为草原露天煤矿区的长周期陆面演变监测提供基础数据。
英文摘要	The soil moisture can be considered as an appropriate indicator to investigate the level of ecological environment disturbance resulting from mining activities in semi - arid grassland. The main objective of this research is to explore the applicability of Chinese HJ - 1B data for LST and soil moisture monitoring around mining-affected areas on the local scale. The JM&S,Qin and Artis methods for temperature retrieval were comparatively analyzed. The relationship space of NDVI - LST was used to generate temperature vegetation dryness index (TVDI). Furthermore,the reference data including in situ soil moisture and MODIS LST products were used for "dry edge" correcting of TVDI. Some conclusions have been reached: The Qin’s mono - window algorithm performs best in LST retrieval from HJ - 1B data; there is a highest correlation between corrected TVDI value with C =0. 3 and in situ soil moisture value; the feature of NDVI - LST space indicates that there is a linear relationship for "wet edge",while the relationship for dry edge,,is conic; the TVDI imagery and LST imagery show different drought conditions of different features. The obvious geographical heterogeneity has been found from the TVDI and LST imagery in this area as well.
